How sustainable am i?

I feel that i am a fairly sustainable living person, whilst at home i always turn the lights off and any electricals off when leaving a room, i put my washing machine on a low temperature and hang my clothes to dry not using a tumble dryer. When taking my rubbish out to the bin i seperate it and make sure i do recycle.

Honestly i tend to use my car an awful lot as i commute to university everyday from Leicester and i do use it alot when at home. I feel that the park and ride is a very good idea and really i should look into using it when going into town and using other public services. When at home i seem to put the heating on quite alot of the time. I also do not use energy saving lightbulbs which really i should do. When i go out and do my weekly shop i dont tend to by the organic fruit and veg because of the price, if it was cheeper i would look into buying it, i would always go out and buy my fruit and veg and not grow my own.

I personally have never really took an interest in global warming and climate change, but i do have a basic knowledge of what it is all about.
I believe that sociciety is right when they talk about using bikes and walking places more often and also saving energy, as it does effect the world.
